Valid EF is just the one function, standardly modeled by those finite initial approximations with the integers bounded above.
How's that? (With "[Virgil's] truly random device assigning each one to be even or to be odd".) The numbers are already even or odd for whether they're congruent to zero modulo two, i.e., integral multiples of two, or not (and if not, exactly and only multiples of halves). That kind of ridiculous misrepresentation serves nothing but to cheapen the discourse in misdirection from matters at hand. What you'd reassign what "even" is, from the integers in order? Here plainly an integer "at random" from between zero and a large bounded quantity has that a reasonable estimate in as to whether it's even is via the outcome of a fair coin toss. Now, this can lead to a discussion on the central limit theorem and alternatives. There's still much for the theory of probability to have developed in the simple theory of attenuation.
Consider this: a bookmaker offers more than two for a wager of one on correctly guessing whether a strongly pseudo-random integer is even. Is not the game a winner with a constant guess of yes? Similarly for correctly guessing whether the result is a multiple of n = three, four, etcetera, with a return > n, do you not see that it's a winner? Is not the bookmaker irrational and soon, starting with finite resources, broke, fairly accepting wagers on those terms? (I'm a capitalist not a gambler.) Half of the integers are even.
Funny, I respond to points with points and you remove them from your replies, in a debate that would be seen as "dropping" the points. Go with the flow. Perhaps you're familiar with rhetoric, and forensic rhetoric? Go with the flow.
And please let it be known I happily and readily address mathematical points, and do, and I don't drop points.
No you fool they're words. You write to bite? Write to enlighten (and gallery, please understand that my goal is to promote mathematical discourse). Quit gumming everybody, quit pushing your pablum on those beyond it, and damnit quit snipping and yipping you obnoxious semi-intellectual poltroon.
And that's generous.
Then, it was just established that the part-whole principle is reasonable, for describing the relative properties of sets and their proper subsets, in their supersets, but that is just peer-reviewed and defended to the thesis board only recently, historically. It's brought into the debate, and debated, showing that when it was verboten, that was wrong.
